Dispatch control messages to callbacks by name.
Declared in <balb_controlmanager.h>
class ControlManager;
| Name | Description |
|---|---|
ControlHandler | Defines a type alias for the function called to handle control messages. The prefix argument is the first space-delimited word read from the message, and the stream argument is the bsl::istream containing the remainder of the message. |
| Name | Description |
|---|---|
ControlManager [constructor] | Create a control manager object. Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used. |
~ControlManager [destructor] | Destroy this object. |
allocator | Return the allocator used by this object to supply memory. Note that if no allocator was supplied at construction the default allocator in effect at construction is used. |
deregisterDefaultHandler | Deregister the callback function previously registered (see registerDefaultHandler) to handle messages with unregistered prefixes. Return 0 on success or a non-zero value otherwise. |
deregisterHandler | Deregister the callback function previously registered to handle the specified prefix. Return 0 on success or a non-zero value otherwise. |
deregisterUsageHandler | Deregister the callback function previously registered to handle "HELP" messages (see registerUsageHandler). Return 0 on success or a non-zero value otherwise. |
dispatchMessage | dispatchMessage overloads |
hasDefaultHandler | Return true if this control manager has a default message handler installed, and false otherwise. |
printUsage | Print to the specified stream the specified preamble text, followed by the registered commands and documentation for this control manager. Note that a newline is appended to preamble in the output. |
printUsageHelper | Invoke printUsage passing the specified *stream and preamble. Suitable for binding using the bdlf::BindUtil package. |
registerDefaultHandler | Register the specified handler to be invoked whenever a control message having an unregistered (case-insensitive) prefix is received by this control manager. Return a positive value if an existing callback was replaced, return 0 if no replacement occurred, and return a negative value otherwise. |
registerHandler | Register the specified handler to be invoked whenever a control message having the specified case-insensitive prefix is received by this control manager. Also register the specified arguments string to describe the arguments accepted by the message, and the specified description to describe its operation; these are printed by printUsage. Return a positive value if an existing callback was replaced, return 0 if no replacement occurred, and return a negative value otherwise. |
registerUsageHandler | Register a handler that, on receipt of a (case-insensitive) "HELP" message, prints to the specified stream a list of this ControlManagers registered commands and their documentation. Return a positive value if an existing callback was replaced, return 0 if no replacement occurred, and return a negative value otherwise. |
operator BloombergLP::bslmf::NestedTraitDeclaration<ControlManager, UsesBslmaAllocator> | Declare that this type uses a bslma allocator. |
